NODDING OFF? Research suggests that later school start times lead to more sleep and better grades.
Teens in California now have less reason to hit the snooze button. This past October, the state passed a law preventing classes from starting before 8 a.m. for middle schools and 8:30 for high schools.
Teens need 8 to 10 hours of sleep every night. But about 58 percent of middle school students and 73 percent of high school students don’t get this amount of shut-eye. By starting school later, kids get to sleep in longer. That can help students stay alert and make it to school on time.
Scientists asked 9,000 high school students when they would prefer classes to start. The graph shows their answers. What percentage answered times later than the earliest start time of high schools in California?
